what does code C1241 indicate in my Toyota Highlander Fourth Generation (2020-present)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off and keys removed.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Repair Wiring

• Inspect Wiring:
  • Visually inspect the ABS wiring harness for frays, breaks, or signs of corrosion.
• Repair or Replace:
  • If damage is found, repair the wiring with appropriate connectors or replace the entire harness if necessary.

3. Check Wheel Speed Sensors

• Remove Wheel:
  • Raise the vehicle and remove the wheel where the wheel speed sensor is located.
• Inspect Sensor:
  • Check the wheel speed sensor for dirt or obstructions.
• Clean or Replace:
  • Clean the sensor with a brake cleaner if dirty. If the sensor is damaged, replace it with a new one.

4. Test ABS Actuator

• Reconnect Battery:
  • Reconnect the negative battery terminal.
• Use Diagnostic Tool:
  • Use an OBD-II scanner to perform an actuator test to ensure the ABS actuator functions correctly.
• Replace if Necessary:
  • If the actuator fails the test, replace it according to the manufacturer's specifications.

5. Final Checks

• Fluid Level:
  • Ensure the brake fluid is at the correct level after repairs are made.
• Test Drive:
  • Perform a test drive to verify that the ABS warning light has cleared and the braking system operates normally.
